Energy Savings of Office Equipment

Simitri HD Toner Fixable at a Low Temperature

In MFPs, heat is needed to fix toner to paper, and the power used for that purpose accounts for more than 60% of total power consumption. Conducting R&D into toner that is fixable at lower temperatures, Konica Minolta developed Simitri HD Toner, a proprietary polymerized toner. The company successfully reduced the fixing temperature by about 25 degrees Celsius compared to conventional models, contributing to the reduction of power consumption.

Moreover, with polymerized toner, energy consumption is also reduced during the production stage to the extent that a pulverization process is not needed compared to the conventional pulverized toner.

IH Fixing System Reduces Standby Power Consumption

In order to start printing from an MFP, the fixing rollers have to be heated to a certain temperature. Konica Minolta uses induction heating (IH) technology, which has high heating efficiency, in its fixing units. This enables rapid heating from a low standby temperature, substantially reducing standby power consumption.

LED Light Source Reduces Power Consumption During Scanning

Konica Minolta uses LED, which has greater power-saving performance than fluorescent lamps, as the light source for scanners in its MFPs. This has also improved scanning speeds, since LED lights increase the brightness of manuscript exposure.

“Power Save” Feature Reduces Power Consumption When Product Not in Use

Konica Minolta equips its MFPs with a “power save” feature that puts the machine into an energy-saving state, such as automatically turning off the control panel display when the machine has not been used for a certain amount of time. This does not hinder everyday work, since the machine automatically returns to normal mode during power save when it receives a fax or a print signal from a PC.

Proximity Sensor That Can Save Electricity Without Lowering Operational Efficiency

Konica Minolta equips its MFPs with a proximity sensor that automatically returns the machine to normal mode from sleep mode just by bringing a finger close to the control panel. This allows energy savings without lowering operational efficiency, as no time needs to be spent pressing buttons to bring the machine out of sleep mode.

Energy-saving Designs That Power Only the Areas Needed

Konica Minolta minimizes power consumption through energy-saving designs that enable power supply only to areas needed for each function—for example, not starting up the printer control panel when printing from sleep mode or not turning on the toner fixing heater when using the scanner or fax.

“Print Preview” to Reduce Misprints

Misprints can be prevented, as it is possible to preview the finished document on the machine’s LCD screen before printing. This saves paper and also reduces wasteful power consumption.

Weekly Timer with a Learning Function

A weekly timer that automatically switches between normal mode and power-saving mode at pre-set times enables efficient electricity savings according to office use, such as at lunchtime, at night, and days off. The machines are also equipped with a learning function that automatically makes corrections when there is a difference between timer settings and actual usage, based on usage data for a four-week period. This enables operational management with greater energy-savings effects.

Eco Dashboard Increases Users’ Environmental Awareness

Graphs showing environmental contribution are displayed to increase users’ environmental awareness. Reductions for different indicators, such as power consumption and use of toner and paper are displayed on the control panel and can be checked by department and user.

Functional Materials Helping Society to Prevent Global Warming

Organic Light Emitting Diode (OLED) Lighting: Next-generation Lighting with Low Environmental Impact

OLED lighting, which uses an organic material that emits light when stimulated by an electric current, has great promise as a next-generation lighting source with low environmental impact. On top of features unavailable in conventional lighting, such as being thin, lightweight, and providing a surface light source, OLED lighting has high energy use efficiency and low heat generation, and does not use mercury like fluorescent lights.

Leveraging its proprietary technology, Konica Minolta has been a pioneer of R&D into practical applications for OLED lighting. In June 2014, it achieved the world’s highest luminous efficiency* for an OLED lighting unit of 139 lm/W, which exceeds that of general LED lighting.

In fiscal 2015, Konica Minolta received the 67th Kinki Chemical Society Award for Chemical Technology for the creation of blue light-emitting phosphorescent materials for OLED lighting and the development of a highly efficient and durable light-emitting device using these materials.

Automotive Thermal Insulation Films Contributing to Reduction of Energy Used for Air Conditioning

Konica Minolta’s automotive thermal insulation films use groundbreaking wavelength control technology to block heat rays and ultraviolet rays. They also cut more than 95% of infrared rays, which is the source of heat, using Ultra Nano particles developed independently. In addition to creating a comfortable in-vehicle environment by substantially reducing the penetration of heat into automobiles, these films contribute to better fuel economy by reducing electricity use for air conditioning.*

Industrial Inkjets Contributing to Energy Savings in the Textile Printing Process

Textile Printer Reducing Electricity Usage through On-demand Production

The inkjet textile printer does not require the plate making and colored size mixing that is needed with conventional screen-printing. It also contributes to the reduction of energy usage, resources usage, and waste, since it enables on-demand production that uses only the amount of ink and material needed. It reduces environmental impact significantly, with a 57% reduction in electricity usage compared to conventional screen-printing. In addition, it helps save energy for operations such as air conditioning and lighting by increasing customers’ production efficiency.

Planetarium Projector Contributes to Energy Conservation

Planetarium Projector Reduces Energy Consumption by Using LED Light Sources

Konica Minolta launched the Infinium Σ with enhanced functions and specifications, significantly reducing energy consumption by using LED light sources instead of a metal halide lamp.
With its LED light sources, the system significantly increases the brightness of the stars, bright stars, planets, sun and moon, improves color reproduction, and reduces energy use (CO2 emissions) by more than 50%. In addition, the adoption of a hydrodynamic-based cooling system and a silent fan suppresses noise like never before.
